High compression models for light gases

摘要

Pfeiffer Vacuum has announced the introduction of its HiPace 700 H turbopumps, which offer very high compression, especially for light gases. With a compression ratio of ≥2·107 for hydrogen, they are designed to generate high and ultra-high vacuum. Due to the high compression ratio, a low residual gas spectrum, which is required for certain mass spectrometry applications, is created in the chamber.
